Harmonized System Code Classification

7304515015
Classification: Tubes, pipes and hollow profiles, seamless, of iron (other than cast iron) or steel: Other, of circular cross section, of other alloy steel: Cold-drawn or cold-rolled (cold-reduced): Other: Other: Suitable for use in boilers, superheaters, heat exchangers, condensers, refining furnaces and feedwater heaters: Of heat-resisting steel
Description: This HS code describes seamless tubes, pipes, and hollow profiles made of iron (excluding cast iron) or steel, specifically those made of other alloy steel with a circular cross-section, cold-drawn or cold-rolled (cold-reduced), and used in boilers, superheaters, heat exchangers, condensers, refining furnaces, and feedwater heaters, made of heat-resisting steel.

Examples of products under this HS code include:

• Heat-resistant steel seamless tubes for boiler applications
• High-temperature alloy steel pipes for heat exchangers
• Cold-drawn stainless steel tubes for condensers
• Seamless alloy steel pipes for refining furnaces
• Alloy steel tubes for feedwater heaters in industrial settings
